How to Convert HEIC to JXL

  1. Upload your HEIC or HEIF files using drag & drop or the file browser. Try our sample HEIC files for testing.
  2. Adjust the quality distance (0 for lossless, 1 for visually lossless recommended).
  3. Set encoding effort - higher values produce smaller files but take longer.
  4. Click "Convert to JXL" and wait for processing to complete.
  5. Download individual files or all as a ZIP archive.
Pro tip: Use our HEIC Analyzer to inspect your files before conversion, or resize images first to reduce file sizes further.

About HEIC and JPEG XL

HEIC Format

HEIC (High Efficiency Image Container) is Apple's default photo format on iOS devices. It offers better compression than JPEG while maintaining quality. However, compatibility can be limited on non-Apple devices. For maximum compatibility, consider converting to JPG.

JPEG XL Format

JPEG XL (JXL) is the next-generation image format designed to replace JPEG, PNG, and GIF. It offers superior compression (up to 60% smaller than JPEG), supports both lossy and lossless compression, progressive decoding, and HDR content. Safari 17+ supports JXL natively. For older browsers, use our JXL to JPG converter.

Benefits of Converting HEIC to JXL

Smaller Files

JXL typically produces 20-40% smaller files than HEIC at equivalent quality.

Superior Quality

Visually lossless compression preserves details that other formats lose.

Future-Proof

JXL is designed for long-term archiving with royalty-free licensing.

HDR Support

Preserves high dynamic range data from modern iPhone cameras.

Frequently Asked Questions

Safari 17+ on macOS and iOS has native JXL support. Chrome and Edge can enable support via browser flags. Firefox support is in development. For universal compatibility, keep JPG versions or use our JXL to JPG converter.

Distance 0 means mathematically lossless - the decoded image is bit-for-bit identical to the original. Distance 1 is "visually lossless" - imperceptible differences that allow 20-40% better compression. For photos, distance 1 is recommended.

At distance 0 (lossless), no quality is lost whatsoever. At distance 1, any differences are imperceptible to the human eye. Even at distance 2-3, JXL maintains better quality than equivalent JPEG compression.

Yes, with the "Preserve EXIF metadata" option enabled, all camera information, GPS coordinates, and other metadata from your HEIC files will be transferred to the JXL output. Use our HEIC Analyzer to view metadata.

Typically 20-40% compared to HEIC at visually lossless quality. HEIC is already well-compressed, so savings are less dramatic than converting from JPG (which can save 40-60%).

We offer many HEIC converters: HEIC to JPG for maximum compatibility, HEIC to PNG for lossless with transparency, and HEIC to ICO for icons.
